WILLIAM Rain COLLIER. 0F AUSTIN,(.tnfxfns.jr4 l f rIsToN-Hnanf'f i Toall whom t may concern:

Be it'. known that I, VILLIAM R. COLLIER, a citizen of the UnitedStates, residing at Austin, in the county of Travis and State of Texas,have invented a new and useful Piston- Head, of which the following is aspecification.

ticularly designed for use in connection with a hydrocarbon engine, oneof the objects of theinvention beingto provide a novel form of ball andsocket connection between the piston rod and the piston head, saidconnection being durable 1n construction,'cheap to manufacture,andeasily applied, the conuection when in position serving to securelyhold together the parts and to permit free movement of'the rod relativeto the piston head. v

With the foregoing and other objects in view, which'will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes inthe preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed, without de parting from the spirit of theinvention.

` ln the accompanying drawings the pre- Y ferred form of the inventionhas been shown ln said drawings Figure 1 is a central longitudinalsection through a piston head embodying the present improvements, theball end of the piston rod being shown in position therein.

Fig. 2 is a section on line 2-2 Fig. i.,

i Fig. 3 is a section on line 3-3 Fig, l.

Referring to the iigures by characters of reference 1 designates apiston head, the same being formed hollow and open at one end. Formedwithin this piston head are radial ribs 2 extending from the closed endv of the piston head to a-point spaced from the open end of said pistonhead.l The inner ends of the ribs are extended inwardly to provideshoulders orseats 3 while thoseportions of the inneredges of the ribsbetween the shoulders 3 and the outer ends of the 'ribs are inclined asate thus to converge toward Vthe .closed end of the piston.

Detachably seated within the piston head is a truste-conical socketmember made up of opposed similar sections and which mem- `speciacat'nmf tettersratet.' "Pamd-pr; Application med August 24, v1917K. i serialNb..iss,o5o.ff l y This 'invention relates to piston heads par-7 ber,when `inserted into the piston head,

will it snugly upon the shoulders 3 and upon v the vinclined edges 4f ofthe ribs 2. The Sections of the socket member are provided with spacedears (3 extending outwardly therefrom and which are adapted to rest uponthe outer ends of the ribs 2. These ears are designed to receive thefastening screws 7 which eX tend 'into the ribs so as to hold the socketmember securely in place. In assembllng the parts the sections socketmember are placed upon opp-@site por tions of a ball 9 .on a piston rodl@ and with manufacture, provides a tight connection between the pistonrod and the head, and allows free movement of the rod relative to thehead. ,i

What is claimed is l. The combination with a hollow piston head open atone end and closed at its other end, and radial ribswithin said head andextending longitudinally thereof, said ribs having their freelongitudinal edges con-V verging toward the closed end of thel pistonhead, of a sectional socket memberinsertible into the head and betweenthel ribs, means for fastening said socket member to the piston head,and a piston rod having a ball end movably engaged bythe sockebmember.

2. The combination with a hollow piston heads and having theirlongitudinal edges converging toward the closed end of the piston head,:there being shoulders on said ribs and adjacent the closed end of thehead, of a Sectional socket member insertible into the head and heldtogether by the ribs, said shoulders constituting abutments for thesocket member, a piston rod having a ball end seated within thesectional socket member, and means for securing saidI socket memheadopen at one end and closed at its .other end, and longitudinal ribswithin the piston lll@ ber t0 the ribs to hold the socket member inengagement with the ball end.

3. The Combination with a holow piston head open at one end and closedet. its oher end, and longtudilm ribs: Within thepisizon head andconverging to rd the Closed end thereof, of a. Sectional socket memberwedged between the ribs and held togethe thereby, e piston rod having abell end plejectng into 10 and adapted to Work Within the Socket member, and mezmswor ietaehably securing the socket member to the ribs,

In testimony that claim the foregoing as my own, have hefeto s xed mysignature 'in 'the presence of two witnesses.
